[GRASS-user] 3D raster color coding

Tue Jun 12 18:55:00 PDT 2018

that worked! thank you. i can see the data using 3D view, in data tab,
select 3d raster at bottom (scroll down), select 3d raster, draw: slices,
shading flat, resolution 1, select wire box.
then i can add slices.  I havent mastered the system yet but i think i am
on the right track now.  thank you very much!
